Global climate change hotspots in terms of multi-risk assessment of hydro-climatic hazards
The natural hazards can have devastating consequences on the society in terms of human health and mortality and also on the ecosystem and the economy. In the last decade, five billion people have been affected by natural disasters resulting in approximately $1 trillion of economic losses around the world. The hydro-climatic natural hazards are becoming more dangerous as a result of climate change and as population and infrastructure continue to increase and occupy areas exposed to higher risks. This underscores the importance of analyzing future hydro-climatic natural hazards to provide an essential foundation for local authorities and policymakers to apply an acceptable level of hydro-climatic hazard risk, to define the regional protection level required and to implement the best mitigation/adaptation plans for the future hazards. This research therefore aims to contribute to a better understanding of how climate change may impact hydroclimatic hazards in the world. The specific objectives of the research are 1) to investigate the impact of climate change on hydro-climatic hazards (i.e., extreme precipitation, streamflow extremes and drought) at the global scale, 2) to assess the uncertainty in the projected changes in hydro-climatic hazards and 3) to perform an integrated analysis of risk and vulnerability at different spatiotemporal scales and identify the climate change hotspots.
